At 7.3K, good results exceeding 10 5 A / cm 2 were obtained. Also, from the surface texture, it was confirmed that the texture of the oxide superconducting film was uniform and dense. FIG. 3 (a) shows Y on a SrTiO 3 film base.
FIG. 3B shows an X-ray diffraction pattern (relationship between analysis angle and intensity) in the case of performing plasma deposition of Ba 2 Cu 3 O −x . FIG. 3B shows YBa 2 Cu 3 O on a MgO base.
The X-ray diffraction pattern in the case of performing plasma deposition of -x is shown. In FIG. 3A, the influence of the SrTiO 3 film base appears because the plasma deposited layer is thin, but it is understood that the result is equivalent to that of FIG. 3B.

By including the above, it is possible to vapor-deposit a desired modifying substance on the surface of the long material to be vapor-deposited and perform the modification. (2) The gas atmosphere inside the vapor deposition chamber is arbitrary, and the vapor phase vapor deposition property can be improved by selecting an oxygen intervening atmosphere such as air or a specific gas atmosphere. (3) The plasma device is connected to a reforming substance supply means for supplying the reforming substance and an air feeding means for feeding the reforming substance by placing it on the air flow, thereby feeding the reforming substance and forming a plasma flow.

(4) Since the modifying substance supply means supplies water or mist, OH groups can be generated on the surface of the long material to be vapor-deposited to form a hydrophilic surface. .. (5) A uniform and dense superconducting coating layer is formed on the surface of a long material to be vapor-deposited in a desired shape by using an oxide superconducting fine particle producing apparatus for supplying oxide superconducting fine particles as the modifying substance supplying means. Then, the superconducting long material can be obtained. (6) By forming a superconducting coating layer on a long material by plasma vapor deposition, it is possible to manufacture a long superconducting material having good superconducting properties while suppressing changes in the composition ratio of oxide superconducting fine particles and the like.
